Hey guys, I have some questions regarding some NES reproductions I'm looking to get and about donor boards.

Basically, I'd like to know the significance of the final two digits in board types.

For example, I have a copy of Infiltrator I'd like converted into Rockman 5 Endless. Infiltrator is

NES-TLROM-02, but Rockman 5 Endless uses NES-TLROM-03 or 04. What is the difference? Does this affect anything? In other words, can I use Infiltrator as a donor cartridge for Rockman 5 Endless?

What about Faxanadu NES-SGROM-02 to Rockman 2 Endless SGROM-03?

When information gathered from the NEScartDB, I've come up with the following. Please let me know if this is correct or I am mistaken in some parts.


Game I want  >   Required board  >     Donor cart
The Goonies 1        NROM-256-02   10 Yard Fight
Dig Dug                NROM-256-02    Gyromite
MegaMari                    UNROM-07        Renegade    
Rockman 2 EL            SGROM-02    Faxanadu            
Rockman 3 EL            TLROM-03     Dirty Harry                
Rockman 4 EL            TGROM-01    Ninja Crusaders
Rockman 5 EL             TLROM-03    Infiltrator or Super Spike V'Ball
Metorid X                    SNROM-03    Spot the videogame
Hammerin' Harry    TLROM-03       Mendel Palace                
Magical Dorophie    TLROM-03       Mendel Palace        
Mario 256 Worlds  NROM-256-01       Super Mario Bros.
Bio Force Ape            TSROM-08   Where's Waldo?
Gradius 1.5 Arcade     TLROM-03      Base Wars

thanks for any help.
